webpack-dev-server的“npm start”错误
我知道这是一个形成问题的可怕的方式，但我已经研究了几个小时，并没有取得任何进展。 一切正常昨天晚上，今天早上我有一个从App Store的更新，使我重新启动，现在我的npm服务器（我试图学习React.js）不起作用。 这是我的错误日志：

- 交换端口
- 恢复git提交
- 用
sudo重新安装节点
没有工作。
从node_modules目录中删除webpack-dev-server并运行npm install webpack-dev-server
感谢评论，我能够解决。 我尝试通过使用npm install重新npm install 。 这没有奏效。 然后我尝试使用npm install webpack-dev-server并出现错误。 它一直说像xyz/abc/node_modules/xyz/node_modules/abc/.bin/file存在。 移动并重试。 我试了几次，最后删除了我的node_modules目录下的整个webpack-dev-server目录并重新安装。 现在一切正常。
顺便说一句，我使用Lynda.com的“React.js基本培训”。 只有包含这个信息的其他人可能有这个问题。
